The Lowdown
Right folks, Rusty here. Let me break down the next couple of weeks for Kennebunk Beach. Gotta be straight with you—it's looking pretty bleak for the most part.
We're kicking off with a long stretch of poor conditions that runs all the way from now, Thursday the 27th of August, through to the end of Monday the 31st. The good news is that it doesn't stay poor forever, but the first decent opportunity doesn't arrive until Wednesday the 2nd of September.
The only window that pokes its head up is on Wednesday, September 2nd. We've got a little bump of new swell coming in from the East at 5ft, with a period of 7 seconds. The wave energy is moderate at best (245). The real key here is that early morning session; we're looking at a glassy, clean surface with light NE winds. It won't be the best surf of your life, but after a week of nothing, it's a glimmer of hope. The water temp is sitting at 66°, which is a touch warmer than normal for this time of year, so the wetsuit might feel a little less restrictive.
The next possible look is Thursday afternoon, the 3rd of September. It's a similar story with 5ft easterly swell (381 energy), and dead calm, glassy conditions. It’s surfable and clean, but still ordinary. That's your lot for the first week.
After that, we're back into the doldrums. Friday the 4th brings clean conditions but the swell drops off fast. And from there the outlook goes quiet with weak, small surf and onshore winds through the second week. There are a few mornings with glass or offshore wind, like Monday the 31st of August, and Saturday the 5th of September, but the swell is just too small (1.0ft to 2ft) to bother.
The long-range stuff from the 6th of September onwards offers a bit more swell, with some days seeing 3ft to 4ft, but the period is short (4-6 seconds) and winds are mostly cross-on or onshore, making for messy, choppy conditions. Nothing to get excited about.
So, the bottom line: don't hold your breath. The only two decent windows are on Wednesday morning, September 2nd, and Thursday afternoon, September 3rd. Everything else is either too small, too windy, or both. It’s a poor run, but it's a fairly consistent pattern for a sheltered beach setup like this. Forecasts can change, so keep an eye on it, but as of now, this is the reality.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
